Most community settlements in Indonesia do not have a household scale of a wastewater treatment plant. Fatal impacts on the environment and human health can occur at any time, including (a) causing environmental damage (disaster), (b) damaging beauty/aesthetics for the scenery will be unpleasant and foul-smelling, (c) polluting water bodies, and (d ) endangering health. The purpose of this study is to optimize the Multi Soil Layering (MSL) System to treat domestic wastewater (greywater) using environmentally friendly materials that are available in Indonesia. The research method used the MSL system with the first variation using a batch system with Hydraulic retention time (HRT) for 24 hours and the second variation using an intermittent system with 3, 6, 9 hours HRT. The results showed that the MSL system was able to eliminate COD well. The highest COD removal efficiency was 93.44% at 9 hours HRT, but the effluent quality did not meet the required quality standards. The development of MSL systems that produces an effluent quality that meets the quality standards needs to be studied further.

Wastewater Quality

Domestic wastewater treatment is one of the environmental problems in Surabaya. Besides causing water pollution, wastewater also causeing health problems. A method to treat wastewater is Communal Waste Water Treatment Plant (WWTP). The effluent of WWTP is then reused by residents. The study aimed to describe the WWTP in Kelurahan Simokerto, Kecamatan Simokerto, Kota Surabaya, and compare wastewater parameters to the regulation. The study is a descriptive observational and cross-sectional research. The method used is interview with WWTP organizer and laboratory examination on 5 samples of influent and effluent parameters include pH, BOD, COD, TSS, oil and grease. All of influent and effluent parameters have already met domestic wastewater quality standards in Peraturan Gubernur Jawa Timur No. 72 Tahun 2013 so the effluent is safe to be discharged into the environment. Since the influent and effluent is below the maximum level of quality standards, the Communal WWTP in Kelurahan Simokerto hasn’t already met standard for an appropriate WWTP. The experts need to do study about wastewater characteristics before building a WWTP so that the appropriate WWTP is obtainable. Moreover, they need to do in-depth study about factors that affect wastewater quality. It’s necessary to arrange detailed SOP for routine operations and maintenance of WWTP accompanied by improvement of understanding of the organizer and citizens about the importance of communal WWTP as well as how to operate and maintain.

Water pollution because of the domestic wastewater produced by the local community and their home industries in a big city, such as Jakarta, has already been inviting many environmental problems since the last ten years. Based on the research done by Directorat General Cipta Karya, Public Works Department RI, domestic wastewater in Jakarta delivers 75% of all pollutants in surface water pollution. Therefore many things should be done to solve those water pollution problems. A lot of environmentally related rules have established in Indonesia, but they are not able to be optimally implemented because of some weaknesses of the environmental rule contents. One of the solving options is to create a perfect regulation system for wastewater management. The laws for home industry wastewater management, especially in big cities, have to be perfectly completed, mainly in the field of standard, operation and procedure, the wastewater quality standard, the adequate and qualified technology, the landscape and building planning and the institutional coordination. If the all environmental regulations are well synchronized, the law enforcement will be simply implemented. By applying them consistently, the water pollution control will be handled well. Keywrods : Environmental Regulation, Home Industry Waste Water, Institutional Coordination
